摘　　要：本文在现代地球系统科学视野下,简要回顾了20世纪国际地幔地球化学学科形成历史;综述了自20世纪70年代以来,中国地幔地球化学发端与发展的历程;强调了在国际岩石圈计划及大陆动力学等计划推进下,以中国大陆岩石圈组成与演化特征研究为重点,先后开展了东部新生代玄武岩及其幔源捕虏体研究、地幔源区地球化学特征及端元厘定、地幔地球化学填图所揭示的地幔源区块体特征以及大陆深俯冲导致的壳幔相互作用和华北克拉通破坏计划与相应研究所取得的进展;其中特别总结了新世纪以来在幔源岩类研究方面的巨大进展,以及在应用非传统稳定同位素、微区原位分析领域以及深地幔超高压矿物研究方面所取得的突破性成果。最后本文强调了现代地球系统科学应回归到它的本来含义,即涵盖深空、深海、深地,从外层空间直至地核的多圈层相互作用及其动力学机制的全方位全过程地球科学,其中,包含核幔相互作用的深部地幔过程,无疑起着主导作用,而地幔地球化学在现代地球系统科学中将依旧作为生力军而不可或缺;同时强调今后应重视拓展微观粒子尺度探索及地球化学基础理论研究的重要性。From the perspective of modern Earth system science,this paper briefly reviews the history of the formation of the international mantle geochemistry discipline in the last century,summarizes the history of the origination and development of China s mantle geochemistry since the 1970s,and emphasizes that under the promotion of the international collaborative programs such as the International Lithosphere Program and the Continental Dynamics Program,the research on the composition and evolution characteristics of the subcontinental lithosphere in China is the focus.We have successively carried out research on Cenozoic basalts and their mantle derived xenoliths in the eastern China,geochemical characteristics and end member determination of mantle source areas,characteristics of mantle source blocks revealed by mantle geochemical mapping,crust mantle interaction caused by deep continental subduction,and North China craton destruction plan and the progress made in the corresponding research,especially summarized the great progress in the study of mantle source rocks since the new century,and the breakthrough achievements in the application of non-traditional stable isotopes,micro area in-situ analysis and deep mantle ultrahigh pressure mineral research.Finally,this paper emphasizes that modern Earth system science should return to its original meaning,that is,a comprehensive and all-around geoscience covering the interaction of multiple spheres and its dynamic mechanism in deep space,deep sea,deep Earth,from outer space to the core of the Earth.Among them,the deep mantle process including the core mantle interaction undoubtedly plays a leading role,and mantle geochemistry will still be indispensable as a new force in modern Earth system science.At the same time,the importance of expanding the exploration of microscopic particle size and the basic theory of geochemistry should be emphasized in the future.
